SPECIFICATION forming part of Letters Patent No. 747,281, dated December 15, 1903. Application filed January 28, 1902. Serial No. 91,645. (No model.)

To all whom it may concern:

Be it known t-hatwe, WILLIAM VOELPEL, ERNST SUCHERT, and ALBIN OEKEL, citizens of the United States, residing at Morton, in the county of Tazewell and State of Illinois, have invented certain new and useful Improvements in Hot-VVater Apparatus; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention has reference to a hot-water furnace or apparatus for heating buildings, &c., and has for its object to simplify and economize in the construction of such apparatus.

A further object of the invention is a hotwater furnace arranged with a return-flue; and it consists in the improved construction, arrangement, and combination of parts constituting a hot-water heating apparatus and a masonry case therefor, the same as illustrated in the accompanying drawings, form: ing a part of this specification, in which Figure l is a vertical transverse section through the apparatus, and Fig. 2 is a longitudinal section of the same.

In the drawings, 1 refers to a masonry case comprising side, top, and rear walls.

2 indicates a saddle boiler, comprising the walls 3 and i, which are riveted together at their free ends to form a water-chamber 5, and 6 is a front casing with a fire-box door 7, a door 8, leading into the ash-pit, and a door or doors 9, communicating with the fine, to be described, the front edge of the boiler abutting against the casing 6 and its rear edge against the rear wall of the masonry.

10 indicates a rectangular casting having the angular portions 11, which are supported by the masonry and upon which rest the lower edges of the boiler, as shown, the main portion of the casting extending up and between and lying adjacent to the matching faces of the boiler, as shown, the casting supporting the grate-bars 12, which may be of the rocking type or of any other form.

13 indicates a flue, which is substantially oval in form and of suitable length and width, comprising the walls 14: and 15, riveted at her upper wall or face of the saddle boiler and the outer upper face of the line, and airtight connections between the walls of the .boiler and the flue are made by the castings or other suitable devices 19, as shown, and the chamber 18 is distinctly separated from the fire-box, referred to as 20, by the partition 21, lying between the rear end of" the flne and rear wall of the masonry, with the ends of the partition 21 abutting against the boiler, the partition situated in a line parallel with the upper edge of the flue forming a chamber 22, communicating with the firebox 20 to permit the products of combustion to pass through the flue into a chamber 23, arranged between the casing 6 and the outer end of the flue, the same being separated from the fire-box by a partition or rest 24, which supports the front end of the flue and is secured to the casing, and from thechamber 23 into the chamber 18 above the fine and into the stack 24, arranged in the rear wall of the masonry and communicating with the chamber 18.

The means which we employ forsupplying, delivering, and returning the water to the boiler and fine is through the feed-pipes 25, entering the lower ends of the saddle boiler upon opposite sides thereof, which connect with pipes 26, the coupling between the pipes 25 and 26 having extensions through which the supply of water is fed to the boiler. 27 is a pipe entering the fine from the lower side, communicating with'the chamber 16 and is connected with leaders which connect with the pipes 26. Thus it will be seen when the original supply is forced into the boiler it will be through the pipes 25 to the saddle boiler and the connections 26 for feeding into the chamber 16 of the flue. From the top of the boiler near its outer end extends a pipe 28, connecting with the chamber 5 of the boiler, and from the top of the flue extends a pipe 29, which communicates with the chamber 16 thereof and passing through the boiler 2 connects in the coupling with the pipe 28, a joint 31 being placed in the .boiler 2and around the pipe 29, making a tight joint in the water-chamber 5, as shown.

Connecting with the pipes 25 and 26 are return-pipes 32 and 33, which may in turn be connected with as many leaders fromthe radiators as desired.

It will be noticed by the peculiar construction and arrangement of the boiler that the heat from the fire-box is direct upon the sides of the boiler and upon the body of the flue, in whose chambers 5 and 16 is retained the wa ter to be heated, which insures quick heating of the water and immediate circulation, and

the products of combustion passing through the flue and back over the same through the chamber 18 apply the heat upon the entire surface of the boiler and flue and in the usual manner will cause a circulation of hot water through the pipe 28, the service-pipes connected therewith, and radiators and the return-pipes 32 and 33, the water in the pipes after having been used through the building being returned in manner shown, all waste being replaced through extensions of the feed-pipes 25. In fact, the direct application of the heat upon the walls of the boiler and flue insures the water being kept warm even when the fire has been forgotten, and the arrangement is such that wood or coal may be burned, as desired.

Having thus fully described our invention,

what we claim, and desire to secure by Letters Patent of the United States, is

1. A hot-Water apparatus comprisingasaddle boiler embedded within a brick casing, a

flue substantially oval in form, suitably supported between the matching walls of the boiler and having its upper portion removed a short distance from the upper wall of the boiler, a water chamber arranged in and forming the wall of the flue, a supply, delivery and return pipes connected with the boiler and flue, substantially as described.

2. A hot-waterapparatus, comprisiugasaddle boiler of the walls 3 and 4 forming a water-chamber 5, a flue formed of the walls 13 and 14 forming the water-chamber 16, the walls 14 abutting the walls 4 of the boiler and grate-bars arranged between the matching walls 4 of the boiler and located above the lower edges of the same, as described.

3. In a hot-water apparatus, the combination with a saddle boiler having vertical side walls, a water-chamber, a tire-box located between the matching walls of the boiler and an oval-shaped flue removed from the inner top wall of the boiler with its outer walls abuttingthe inner matching side Walls of the same, air-tight connections between the same, and partitions arranged between the boiler and flue for directing the combustible material through the flue and to return it above the same to the stack, and supply and return pipes connecting the boiler and flue, as described.

4. In combination in a hot-water apparatus, a boiler substantially saddle in form having the chamber 5, a flue having open ends and the walls 13 and 14: between which is arranged a chamber 16, a fire-box arranged beneath the flue, and the arrangement of the flue with reference to the top wall of the boiler forming a chamber 18, supply-pipes of the boiler and flue connected with each other and return-pipes for said boiler and flue, substantially as described.

5. In combination with the boiler 2 substantially as shown, the oval-shaped flue 15 arranged between the walls of the boiler to form the chamber 18, and partitions 21 and 24: for directing the combustible material into the rear of the flue and out of the front end thereof to return above the same through the chamber 18 and thence into the stack, the pipe 28 leading outfrom the top of the boiler, the pipe 29 leading out from the top of the flue through the walls of the boiler and connecting with the pipe 28, the pipe 25 leading into the lower ends of the boiler and the pipe 27 leading into the bottom of the flue and the pipes 25 and 27 connected, substantially for the purpose described.

In testimony whereof we affix our signatures in presence of two witnesses.
